Earlier this year, the White House requested $1.9 billion from Congress to combat the Zika virus at home and abroad. While Congress debated, some funds previously allocated for the Ebola crisis -- and other projects at the National Institutes of Health -- were shuffled to allow research for fighting the disease. But those funds are running out. Despite that, the Senate rejected a GOP-led funding package before Congress left town for their seven week summer recess.

With Zika funding uncertain, Director of National Institute of Allergy and Infectious Diseases Anthony Fauci spoke with CQ Roll Call about what his department needs and when.

The Senate Homeland Security and Governmental Affairs Subcommittee on Investigations holds a hearing on issues with procedures used by the Department of Health and Human Services to handle unaccompanied immigrant children arriving in the United States.

Officials from the Department of Health and Human Services are among the witnesses expected to testify.
